Radiation from hands-free mobile phones can be reduced to virtually zero by a simple tiny magnetic bead which costs a few pence, a government adviser says. Professor Lawrie Challis said clipping a ferrite bead on kits stops the radio waves travelling up the wire and into the head. He called on the mobile phone industry to start using them "as standard".

The beads, which often measure less than 1cm in diameter, are commonly used to stop data interference in computers.
Professor Challis, who is chairman of the Mobile Telecommunications and Health Research Programme, told BBC News: "There is no evidence yet that mobile phones are harmful to health but people have not been using them long enough for us to be sure.
